Bit 7: RX_MIN_ENFORCE enables the enforcing of a minimum frame size. When high, frames with fewer bytes are discarded. When low, no minimum frame size is enforced.

Bits 6-0: RX_MIN_SIZE [6:0] specifies the minimum Ethernet frame size allowed in bytes. Frames with a payload (preamble and SFD excluded) smaller than this value are discarded.
